Lightsaber Glow Variation

So once I've made a lightsaber with a white layer masked out and a neon glow effect applied, what would be the best way to make the beam vibrate a little bit instead of just looking the same. Would I just go about making about 2 keyframes with a small difference in glow value and then copy and paste them over the whole thing, or is their a simpler way? Thanks!

Hi Guys,If you duplicate the plane layer and apply the "Flicker" filter to a second glow layer under the first one and set it correctly the glow flickers.
